Water temp safety

Postby neuman5022 » Thu Dec 07, 2017 2:38 pm

Hello guys

I read that water temp is very important for tube's life.

Is there a way to have a water temp meter to stop the laser from firing when it gets under or over a specific temp (Sort of like the flow switch)

If yes - how do I connect it ?

Many thanks

There isn’t. Your chiller should be able to cope with the laser though. 15-25 degrees is the safe range. Don’t fire it under that temperature you can thermally shock the tube and end up with a nice crack.

If you are using a buffer ( 20ish litre tank of water ) then you might be able to buy some kind of alarm or build one. You might also want to wrap the tank in insulation to keep it cool in the summer and warm in the winter.

You don't want to go too low either because condensation could happen if temperature is too low (closed to dew point). I'll suggest 23~25'C is good range for the laser tube.

Re dew point. That depends on the relative humidity in the room. It doesn’t have to be 24-25 degrees.

Hi SWMS, I didn’t mean the dew point was 24-25’C

What I mean was if the water temperature was cold closed enough to dew point(could be 8, 10,12,15...as you said about the relative humidity), condensation may occurred. Sorry for the confusion
